Completely! A take a look at mild looks as if a screwdriver with a pointy pointed finish, and include a small bulb and a grounding twine or cable. It really works by means of grounding the bulb, and as soon as it is available in touch with an influence supply, it is going to whole the circuit and lightweight the bulb.
